[0002] At present, for the monitoring system of the wheel slippage of the cement plant rotary kiln, the wheel slippage control is extremely important. If the wheel slippage of the rotary kiln is not well controlled, it will seriously affect the normal operation of the rotary kiln, affect the service life of the refractory bricks, and even cause serious damage to the rotary kiln carcass, resulting in property losses. At present, the control of the wheel slippage of the rotary kiln is still in the manual control mode on site, which is extremely inconvenient to operate. Summary of the invention
[0003] The invention provides a rotary kiln operation monitoring device with a wheel slippage detection function, which solves the technical problem of inconvenient rotary kiln slippage measurement in the prior art.
[0004] Some implementation plans adopted to solve the above technical problems include:
[0005] A rotary kiln operation monitoring device with a wheel slippage detection function comprises a frame and a rotary kiln body arranged on the frame, the frame is provided with a driving mechanism for driving the rotary kiln body to rotate, the driving mechanism comprises a front gear set and a rear gear set arranged on the frame, the front gear and the rear gear set each comprise two gears rotatably connected to the frame, the rotary kiln body is respectively provided with a gear ring meshing with the front gear set and the rear gear set, one end of the frame is provided with a motor for driving one of the gears in the front gear set to rotate, the front gear set drives the rear gear set to rotate through the gear ring arranged on the rotary kiln body, and the rear gear set is rotatably connected to the frame through a rear gear shaft;
[0006] The frame is provided with a body detector for detecting the slippage of the rotary kiln body and a shaft detector for detecting the slippage of one of the rear gear shafts, the body detector includes a body probe, the rotary kiln body is provided with a convex block for triggering the body probe, the rotary kiln body rotates through the convex block to push the body probe to swing to obtain a body measurement signal;
[0007] The shaft detector comprises a shaft probe, wherein one of the rear gear shafts is provided with a trigger body, and the rear gear shaft rotates through the trigger body to drive the shaft probe to swing to obtain a shaft measurement signal;
[0008] The frame is also provided with a main body counter for measuring the main body measurement signal and an axle body counter for measuring the axle body measurement signal. The frame is also provided with an alarm and a controller. The controller controls the operation of the alarm. The main body counter and the axle body counter both communicate with the controller. When the controller receives N axle body measurement signals but does not receive the main body measurement signal, the controller controls the operation of the alarm.
[0009] During the rotation of the rotary kiln body, the convex block contacts the body probe once for each rotation, and the body counter measures the value once. For each rotation of the rotary kiln body, the rear gear shaft needs to rotate at least two times. At this time, for each rotation of the rear gear shaft, the trigger body contacts the shaft probe once, and the shaft counter measures the value once.
[0010] During normal operation, the number of revolutions of the rotary kiln body can be easily detected by the body probe, so that the slip of the rotary kiln can be easily measured. When the driving mechanism of the rotary kiln body fails, the rear gear shaft may rotate, but the rotary kiln body does not rotate. At this time, an abnormal situation occurs. The body counter still fails to measure the body measurement signal after the shaft counter measures the value for many times, and the controller controls the alarm to send an alarm message. The stability of the rotary kiln during operation is improved.
[0011] The body measurement signal is formed by using a convex block in conjunction with a body probe, and the shaft measurement signal is formed by using a trigger body and a shaft probe. Compared with using electronic components to form signals, the mechanical signal formation method saves detection costs, and the rotary kiln works stably during operation and is not easily disturbed, thereby improving the accuracy of detection.
[0012] Preferably, the protrusion and the rotary kiln body are of an integrated structure, and the protrusion smoothly transitions to the rotary kiln along the circumferential side wall of the rotary kiln body.

[0015] The main body probe has a reasonable structure and is easy to assemble, which reduces the use cost of the main body probe and is easy to maintain.
[0016] Preferably, the main body measurement frame includes two vertical plates, and an installation space for installing the main body measurement rod is formed between the two vertical plates. The main body measurement rod is rotatably connected to the installation space via a first axis.

[0018] Preferably, the main body measuring rod is further provided with a mounting ear for mounting the main body measuring wheel, the main body measuring wheel is rotatably connected to the mounting ear via a second axis, and the mounting ear and the main body measuring rod are an integrated structure.
[0019] The measuring wheel of the main body rotates flexibly.
[0020] Preferably, a counterweight is provided at one end of the main body measuring rod close to the rotary kiln body, and the counterweight is fixed to the main body measuring rod by a screw.
[0021] The setting of the counterweight block enables the main body measuring wheel to have good contact performance with the rotary kiln body, and further enables the main body measuring wheel to rotate flexibly.
[0022] Preferably, the trigger body is a cam, and the trigger body is fixed to one of the rear gear shafts via a key.
[0023] The trigger body has a simple structure and is easy to process, thereby reducing the use cost of the trigger body.
[0024] Preferably, the shaft measuring probe includes a shaft measuring rod and a shaft mounting frame for mounting the shaft measuring rod, the shaft measuring rod is rotatably connected to the shaft mounting frame via a third axis, the shaft mounting frame is fixed to the frame, the shaft measuring rod is provided with a shaft measuring wheel in contact with the trigger body, and the wheel measuring wheel is rotatably connected to the shaft measuring rod via a fourth axis.

[0026] Preferably, a counterweight is provided at one end of the shaft measuring rod close to the trigger block, and the counterweight is fixed to the shaft measuring rod by a screw.
[0027] The provision of the counterweight increases the pressure between the shaft measuring wheel and the trigger body, thereby improving the measurement accuracy of the shaft measuring wheel.
[0028] Preferably, the main body measuring wheel and the shaft body measuring wheel are both provided with patterns that increase the friction coefficients of the main body measuring wheel and the shaft body measuring wheel.
[0029] The shaft measuring wheel and the trigger block have sliding friction, and the body measuring wheel and the rotary kiln body have sliding friction, which prolongs the service life of the shaft measuring wheel and the body measuring wheel. The shaft measuring wheel and the body measuring wheel are not easy to slip.
[0030] Compared with the prior art, the rotary kiln operation monitoring device with wheel slippage detection function provided by the present invention has the following advantages:
[0031] During the rotation of the rotary kiln body, the convex block contacts the body probe once for each rotation, and the body counter measures the value once. For each rotation of the rotary kiln body, the rear gear shaft needs to rotate at least two times. At this time, for each rotation of the rear gear shaft, the trigger body contacts the shaft probe once, and the shaft counter measures the value once.

When the driving mechanism of the rotary kiln body fails, the rear gear shaft may rotate, but the rotary kiln body does not rotate. At this time, an abnormal situation occurs. The body counter still fails to measure the body measurement signal after the shaft counter measures the value for many times, and the controller controls the alarm to send an alarm message. The stability of the rotary kiln during operation is improved.
[0033] The body measurement signal is formed by using a convex block in conjunction with a body probe, and the shaft measurement signal is formed by using a trigger body and a shaft probe. Compared with using electronic components to form signals, the mechanical signal formation method saves detection costs, and the rotary kiln works stably during operation and is not easily disturbed, thereby improving the accuracy of detection.
